Description

Beschreibungdescription
Kontaktträger zum Einbau in einen Lenkradkörper eines Automobils Die Erfindung bezieht sich auf einen Kontaktträger zum Einbau in eine Lenkradnabe eines Automobils mit einem Isolierstoff- körper, damit verbundenen Leiterbahnen und mit zumindest einem Schaltkontakt, der aus zwei gegeneinander federnd beweglichen Kontaktgliedern gebildet und mittels eines Stößels be- tätigbar ist, wobei der federbelastete Kontaktträger mittels Distanzbolzen mit Abstand an einem stationären Basisteil des Lenkrads gehalten' ist und wobei der Schaltkontakt durch Drücken des Kontaktträgers gegen das Basisteil betätigbar ist.Contact carrier for installation in a steering wheel body of an automobile The invention relates to a contact carrier for installation in a steering wheel hub of an automobile with an insulating body, associated conductor tracks and with at least one switching contact, which is formed from two spring-loaded contact members and by means of a plunger - is tätigbar, wherein the spring-loaded contact carrier is held by means of spacer bolts spaced on a stationary base part of the steering wheel ', and wherein the switching contact is actuated by pressing of the contact carrier against the base part.
Eine derartige Anordnung ist z.B. durch die EP 0953480 A bekannt geworden. Danach ist das Basisteil als separate, im Lenkrad befestigte metallische Stützplatine ausgebildet, die mit angespritzten Kunststofflaschen versehen ist, an denen der Stößel bzw. die Führungsbuchsen für die an den Kontakt- träger angeschraubten Distanzbolzen ausgeformt sind. Der Kontaktträger weist zur Stützplatine hin vorstehende, den stationären Stößeln gegenüberliegende Dome auf, in die Hupenschalter eingesetzt sind. Der Kontaktträger ist an einem Airbagge- häuse befestigt, das durch Druck auf seine aufgesetzte Ab- deckplatte zusammen mit dem Kontaktträger zur Stützplatine hin eindrückbar ist . Dabei dringen die Stößel in die Dome ein und betätigen die Tasten der Hupenschalter.Such an arrangement is e.g. made known by EP 0953480 A. The base part is then designed as a separate metal support plate fastened in the steering wheel, which is provided with molded plastic tabs on which the plunger or the guide bushes for the spacer bolts screwed onto the contact carrier are formed. The contact carrier has domes which protrude towards the support plate and are opposite the stationary plungers and into which horn switches are inserted. The contact carrier is fastened to an airbag housing which, together with the contact carrier, can be pressed toward the support plate by pressing on its cover plate. The plungers penetrate the domes and press the buttons on the horn switches.
Der Erfindung liegt die Aufgabe zugrunde, die Kontaktanord- nung zu vereinfachen.The object of the invention is to simplify the contact arrangement.
Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Durch die unmittelbare Lagerung des Kontaktträgers am Lenkradkörper mittels der in diesen eingeschraubten Distanzbolzen sowie durch die Anordnung des Stößels am Kontaktträger ist es möglich, auf einen separaten Stützkörper zu verzichten. Alle Funktionselemente sind aus- schließlich dem Kontaktträger in definierter Weise zugeordnet, was die Montage erheblich vereinfacht. Der Schaltabstand zur Oberseite des Bodens wird lediglich durch die Länge der Distanzbolzen und die Höhe des Stößels bestimmt, der z.B. als Betätigungsstößel eines im Kontaktträger befestigten Tast- Schalters ausgebildet sein kann und unmittelbar auf den ebenen Boden aufsetzt, wobei ein galvanischer Kontakt zum Boden vermieden wird.This object is achieved by the features specified in the characterizing part of claim 1. Due to the immediate storage of the contact carrier on the steering wheel body by means of the spacer bolts screwed into it and by the arrangement of the tappet on the contact carrier, it is possible to dispense with a separate support body. All functional elements are exclusively assigned to the contact carrier in a defined manner, which considerably simplifies assembly. The switching distance to the top of the floor is only determined by the length of the spacer bolts and the height of the plunger, which can be designed, for example, as an actuating plunger of a push-button switch fastened in the contact carrier and is placed directly on the flat floor, avoiding galvanic contact with the floor ,
Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den in den Ansprüchen 2 bis 4 gekennzeichneten Merkmalen.Advantageous further developments of the invention result from the features characterized in claims 2 to 4.
Bei der Weiterbildung nach Anspruch 2 entfällt der separate Tastschalter. Die Kontaktglieder sind integraler Bestandteil des Stanzgitters. Das bewegliche Kontaktglied ist an diesem als einfache abgebogene Zunge ausgebildet, an der der Stößel im Zuge des Umspritzens des kompletten Stanzgitters ohne Mehraufwand angebracht werden kann.In the development according to claim 2, the separate push button switch is omitted. The contact elements are an integral part of the lead frame. The movable contact member is designed on this as a simple bent tongue, on which the plunger can be attached without additional effort in the course of overmoulding the entire lead frame.
Die nachgiebige Kontaktzunge nach Anspruch 3 ermöglicht das Aufsetzen des beweglichen Kontaktglieds noch vor dem Erreichen der Endstellung des Kontaktträgers und somit eine sichere Kontaktgabe. Außerdem ergibt sich durch die schräge Auf- setzrichtung eine Gleitbewegung mit entsprechendem Selbstreinigungseffekt .The resilient contact tongue according to claim 3 enables the mounting of the movable contact member before reaching the end position of the contact carrier and thus a reliable contact. In addition, the sloping mounting direction results in a sliding movement with a corresponding self-cleaning effect.
Die Weiterbildung nach Anspruch 4 ergibt eine konstruktive Vereinfachung, bei der der formstabile Kontaktträger eine leichtere Ausbildung des Airbaggehäuses ermöglicht. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher erläutert. Es zeigen:The development according to claim 4 results in a constructional simplification, in which the dimensionally stable contact carrier enables a lighter design of the airbag housing. An embodiment of the invention is shown in the drawing and is explained in more detail below. Show it:
Figur 1 schematisiert einen Schnitt durch ein Lenkrad eines Automobils mit einem Kontaktträger in einer Ruhestellung, Figur 2 einen vergrößerten Ausschnitt II aus Figur 1 mit dem Kontaktträger in einer Schaltstellung, Figur 3 eine Draufsicht auf einen Teil eines Stanzgitters des Kontaktträgers nach Figur 1 in einer frühen Bearbeitungsphase, Figur 4 eine perspektivische Ansicht des Stanzgitters nach Figur 3 in einer späteren Bearbeitungsphase1 schematically shows a section through a steering wheel of an automobile with a contact carrier in a rest position, FIG. 2 shows an enlarged section II from FIG. 1 with the contact carrier in a switch position, FIG. 3 shows a top view of a part of a lead frame of the contact carrier according to FIG. 1 at an early stage Processing phase, Figure 4 is a perspective view of the lead frame according to Figure 3 in a later processing phase
Nach Figur 1 weist ein an einer Lenksäule 1 befestigbarer muldenartiger Lenkradkörper 2 eines Automobils einen ebenen Boden 3 mit Befestigungslöchern zum Einschrauben von Distanzbolzen 4 auf. Über dem Boden ist ein plattenartiger Kontakt- träger 5 angeordnet, der mit Führungsbohrungen 6 für die hindurchragenden Distanzbolzen 4 versehen ist. Diese umgebenden Druckfedern 7 sind zwischen dem Kontaktträger 5 und dem Boden 3 verspannt und drücken den Kontaktträger 5 gegen Köpfe 8 der Distanzbolzen 4. Auf der dem Boden 3 abgewandten Oberseite des Kontaktträgers ist ein Airbagmodul 9 befestigt. DurchAccording to FIG. 1, a trough-like steering wheel body 2 of a motor vehicle, which can be fastened to a steering column 1, has a flat bottom 3 with fastening holes for screwing in spacer bolts 4. A plate-like contact carrier 5 is arranged above the floor and is provided with guide bores 6 for the spacer bolts 4 projecting through it. These surrounding compression springs 7 are clamped between the contact carrier 5 and the base 3 and press the contact carrier 5 against heads 8 of the spacer bolts 4. An airbag module 9 is fastened on the upper side of the contact carrier facing away from the base 3. By
Druck auf dessen äußere Gehäuse bdeckung kann das Trägerteil 5 gegen die Kraft der Druckfedern 7 zum Boden 3 hin verschoben werden.Pressure on the outer housing cover, the support member 5 can be moved against the force of the compression springs 7 to the bottom 3.
Das Trägerteil besteht aus einem inneren, Leiterbahnen bildenden Stanzgitter 10, das mit einem Kunststoffköper 11 plattenartig umspritzt ist, wobei eine strichpunktierte Linie die Lage eines optionalen Verstärkungsblechs 12 zur Bildung eines Sandwichs andeutet . Eine federnd bewegliche Zunge 13 und eine stationäre Kontaktzunge 14 des Stanzgitters 10 ragen in eine Freimachung 15 des Kunststoffkörpers 11 sich gegenseitig mit Abstand überlappend hinein und bilden Kontaktglieder eines Schaltkontakts. Die nach unten abgebogene bewegliche Zunge 13 ist nahe an ihrem Kontaktende isolierend mit einem Stößel 16 umspritzt, der zum Boden 3 hin aus der Freimachung 15 herausragt .The carrier part consists of an inner, stamped grid forming conductor tracks 10, which is overmolded in a plate-like manner with a plastic body 11, a dash-dotted line indicating the position of an optional reinforcing plate 12 to form a Suggests sandwiches. A resiliently movable tongue 13 and a stationary contact tongue 14 of the lead frame 10 protrude into a clearing 15 of the plastic body 11 mutually overlapping and form contact members of a switching contact. The downwardly bent movable tongue 13 is encapsulated in an insulating manner close to its contact end with a plunger 16, which protrudes toward the floor 3 from the clearance 15.
Nach Figur 2 ist der Kontaktträger 5 in Richtung des dargestellten Pfeils soweit gegen den Boden 3 gedrückt, dass der Stößel 16 auf dem Boden 3 aufsitzt und die bewegliche Zunge 13 im Kontaktträger bis zum Kontakt mit der stationären Kontaktzunge 14 federnd nach oben biegt. Dadurch werden die bei- den getrennten Leiterbahnen des Stanzgitters elektrisch miteinander verbunden und wird der Schaltkontakt zur Erzeugung eines Hupsignals geschlossen.According to FIG. 2, the contact carrier 5 is pressed against the base 3 in the direction of the arrow shown so far that the plunger 16 rests on the base 3 and the movable tongue 13 in the contact carrier resiliently bends upwards until contact with the stationary contact tongue 14. As a result, the two separate conductor tracks of the lead frame are electrically connected to one another and the switch contact is closed to generate a horn signal.
Figur 3 zeigt das Stanzgitter 10 als flache Platine vor dem Umspritzen mit dem Kunststoffkorper. Das stationäre Kontakt- glied ist an einem inneren Teil 17 des Stanzgitters 10 als die freiragende Kontaktzunge 14 ausgebildet, die in die Nähe der Zunge 13 ragt. Diese bildet an einem äußeren Teil 18 des Stanzgitters 10 das bewegliche Kontaktglied und soll nach un- ten in die strichpunktiert angedeutete Stellung abgewinkelt werden, in der sie von der stationären Kontaktzunge 14 überlappt wird. Die beiden Teile 17 und 18 sind durch schmale Stege 19 zusammengehalten, die beim Umspritzen freigehalten und danach durchgetrennt werden.FIG. 3 shows the leadframe 10 as a flat circuit board before it is encapsulated with the plastic body. The stationary contact member is formed on an inner part 17 of the lead frame 10 as the cantilevered contact tongue 14 which projects into the vicinity of the tongue 13. This forms the movable contact member on an outer part 18 of the lead frame 10 and is to be angled downward into the position indicated by the dash-dotted lines in which it is overlapped by the stationary contact tongue 14. The two parts 17 and 18 are held together by narrow webs 19, which are kept free during injection molding and are then severed.
Diese Phase ist in Figur 4 dargestellt, wobei aus Gründen der besseren Anschauung der Kunststoffkorper weggelassen ist. Die bewegliche Zunge 13 ist beim Umspritzen des Stanzgitters 10 mit dem Stößel 16 versehen und rechtwinkelig nach unten in die Bodenrichtung abgebogen worden. Dabei gelangt das freie Ende der Zunge 13 mit Abstand unter die Kontaktzunge 14. Beim Aufsetzen des Stößels 16 auf den Boden 3 (Fig. 2) kommen die beiden Zungenenden in Kontakt . Beim weiteren Eindrücken des Kontaktträgers 5 kann die Kontaktzunge 14 nach oben ausweichen. This phase is shown in FIG. 4, the plastic body being omitted for the sake of clarity. The movable tongue 13 is when the lead frame 10 is extrusion-coated provided with the plunger 16 and bent at right angles downwards in the direction of the floor. The free end of the tongue 13 comes under the contact tongue 14 at a distance. When the plunger 16 is placed on the base 3 (FIG. 2), the two tongue ends come into contact. When the contact carrier 5 is pressed in further, the contact tongue 14 can deflect upwards.
